The evidence suggests that he is. He gives yet another of his diatribes about the need to cut Medicare, Medicaid, and Social Security in order to advance his grand agenda for the country. Of course Social Security is financed by its own designated tax and is projected to be fully solvent for the next quarter century, so it is a bit bizarre to have this one on the list.
More importantly, the entire budget problem is the result of a broken health care system. This is why serious people point to the need to fix the health care system, which is the real source of the country's projected long-term budget problem. Of course the current shortfall is the result of the collapse of the housing bubble. But Friedman has not heard about that.
